LLAW’s NUCLEAR WORLD NEWS TODAY and the GLOBAL RISKS & CONSEQUENCES TOMORROW

In My Opinion:

Trump makes a huge mess of everything he tries to do, and this is just another serious blunder that decreases the entire world’s former trust, appreciation, reliance, etc.

I’ve jotted down a few abbreviated phrases and comments from the article(s) that tell us that Trump is rapidly destroying America’s global leadership and reputation over his insane self-aggrandizing ambitious desire to become a Putin-style dictator over a huge part of the globe: A recent visit to Greenland by Vice President J.D. Vance created an uproar, and on Wednesday, Danish and Greenlandic officials met on the island in a show of unity against Trump’s repeated calls for U.S. annexation.

Asked about the frigid island, Cavoli made it clear he was talking about the military value of it and not the Trump administration’s policy of trying to assume Greenland from Denmark. Another interjection from the article(s): “Notice that this is really all about him, and his fantasies about himself. Every American should cringe deeply . . .” ~llaw

Greenland “Absolutely Critical” For Hunting Russian Submarines: Top U.S. General In Europe

Gen. Christopher G. Cavoli, the top U.S. general in Europe, testified that Greenland is vital to U.S. national security.

As U.S. President Donald Trump continues to seek control of Greenland, the top U.S. military commander in Europe said the massive island is vital to America’s national security. The main issue, he said, is that Greenland’s geographic location makes it a key landmass from which to track Russian submarines before they have a chance to disappear into the Atlantic Ocean and potentially endanger the East Coast. You can read more about the strategic importance of Greenland in our deep dive here.

“Access to the airspace and water space found in Greenland is absolutely critical for the United States,” said U.S. Army Gen. Christopher G. Cavoli, NATO’s Supreme Allied Commander Europe (SACEUR) and head of U.S. European Command. Cavoli addressed the security value of Greenland during testimony before the Senate Armed Services Committee on Thursday. Asked about the frigid island, Cavoli made it clear he was talking about the military value of it and not the Trump administration’s policy of trying to assume Greenland from Denmark.

“The key there is it forms the western border of the Greenland, Iceland, UK (GIUK) gap, which is that body of water through which Russian submarines from the Northern Fleet in Murmansk come up and then down through that gap,” Cavoli stated. Murmansk is home to some of Russia’s most capable submarines, like the Yasen-M class nuclear-powered cruise missile carrying Kazan.

The threat of Russian submarines in the Atlantic has been so great that in 2021 the U.S. Navy established a dedicated anti-sub task group of Arleigh Burke-class destroyers that was officially named Task Group Greyhound, which you can read more about here. The increasing Russian submarine activity sparked a warning five years ago from a top U.S. Navy officer that the East Coast was no longer a safe haven for the sea service’s ships and submarines.

The value of the GIUK Gap is not lost on Russia, either. In 2019, it launched its largest drill since the Cold War, sending at least 10 submarines from Murmansk through that region.

“The goal for some of the submarines is to get as far out into the Atlantic as possible without being discovered,” Norwegian news outlet NRK reported at the time.

The entire voyage from their Northern Fleet bases in the Murmansk region was submerged.

“Russia’s goal is to show that they are able to threaten the U.S. East Coast,” the publication noted. “Russia wants to say that ‘this is our sea,’ we can do this. We are able to reach the United States… They want to test the West’s ability to detect and handle this…”

Beyond offensive maneuvers, Russian submarines could also flood into the GIUK Gap and the waters off Norway in a defensive posture to keep U.S. submarines and surface combatants from pushing northward during a crisis. This would protect strategic Russian naval ports on the Barents Sea, Russia’s ballistic missile boats patrolling the northernmost latitudes and hiding under the polar icecap, and its increasingly strategic territorial holdings in the Arctic. It could also isolate NATO allies in Northern Europe from naval assistance during a crisis.

With all these considerations in play, Cavoli told senators that not having a strong U.S. presence in Greenland is a dangerous prospect. It makes up part of the northern section of the GIUK gap , which is bisected by the far smaller island of Iceland. With just 200 miles between the southeastern coast of Greenland and Iceland, this an important choke point. This area of the GIUK gap is located about 1,000 miles southeast of the Pituffik Space Force Base, the only U.S. military facility on the island. Formerly named Thule Air Base, it hosts an array of early warning radars and carries out regular flying operations.

Once Russian submarines “get past that gap, they break out into the Atlantic,” Cavoli pointed out. “It becomes very tough to track them. It’s a vast expanse. There’s some acoustic things about the underwater geography that make it pretty tough.”

“From those positions that they can achieve, they can hold the U.S. homeland at risk several important targets with land attack cruise missiles,” the general added.

Still, there are several places on Greenland where the U.S. and NATO allies can increase their anti-submarine capabilities without taking over the entire island. That begs the question of why expend the enormous diplomatic and potentially financial capital to acquire it? Iceland also has a regular detachment of anti-submarine warfare aircraft from the U.S. that covers the GIUK gap, making access for these operations in Greenland seem like more of a convenience than a necessity.

Tracking submarines may be seen as a major part of Greenland’s strategic value, but its location addresses several other important military needs. The radar arrays at Pituffik provide critical early warning of Russian ballistic missile attacks, giving the president and military more time to react. And should an adversary like Russia or China take it over, or even establish a major presence there, it could enable the placement of stand-off weapons just 1,300 miles from the United States.

Cavoli’s comments come amid a roiling international controversy, pitting two close NATO allies against each other. Greenland is governed by Denmark and Trump recently repeated his stance that military action is not off the table to take the island. The president’s interest in Greenland dates back to his first term when he announced he was considering purchasing it.

A recent visit there by Vice President J.D. Vance created an uproar, and on Wednesday, Danish and Greenlandic officials met on the island in a show of unity against Trump’s repeated calls for U.S. annexation.

Meanwhile, U.S. Secretary of State Marco Rubio met with Danish Foreign Minister Lars Løkke Rasmussen in an effort to calm the relations. During that meeting, Rubio reaffirmed the “strong relationship” between the U.S. and Denmark, the State Department stated.

While the politics of the situation is fraught and the future murky, it is crystal clear that Greenland has significant military value.
